  • Post in thread: Outfitting ORV 280RKS with Solar

    The ORV 280RKS is heavy at 8,690 dry and 11,000 GVWR. The Nash 23D was 5,000 dry and 7,000 GVWR. My 1997 F250 has to work hard to pull all of that weight in the mountains!

    This is my first post here. I have been reading others posts for a couple months. I am a full time RV'R since 2015 and purchased my second trailer, a used 2021 Outdoors RV 280RKS, May 2023. My first trailer had 3 x 100 watt Renogy monocrystalline panels with a Schneider (Xantrex) C40...
  • Post in thread: Mixing MC4 Connectors

    I know this subject has been discussed in the past and I've read several threads on the topic. I purchased 12 x 100 watt monocrystalline compact Renogy panels on sale ($130 a pair) last year and I plan on installing them on the roof of my travel trailer. I would like to use 8 AWG wire for the...

    Mattb4 and zanydroid thanks for the replies. I realize 10, 12, and 14 AWG are rated high enough for my system. I would like to use 8 AWG where ever possible pre charge controller to keep voltage drop to a minimum. Crimping dies for 8 AWG MC4 connectors are available for the Staubli crimper...

    Thanks for the input. Windy Nation sells premade and custom length 8 Awg cables with "Staubli or equivalent MC4 connectors". I will most likely use them. A forum member posted a video of a failed connector (Windy Nation to Renogy) but mentioned he had disconnect it several times. That's why...

    Each string will have a 10 amp inline MC4 fuse; stated in my original post. I prefer 2S3P over 3S2P to minimize potential shading impacts. The AC on my RV roof will shade panels early and late in the day.

    Thanks for your reply all your points are appreciated. I went with the 150/60 after crunching the numbers. On a cold sunny day at high altitude it's possible I could get around 110 amps. I don't want to waste any charging capacity so I went with two 150/60 controllers. Since I can't run both...
  • Post in thread: Mixing MC4 Connectors

    I emailed Windy Nation a few weeks ago and asked if they had heard of any compatibility issues between the MC4 connectors they use and other brands of MC4 connectors. I also asked what brand they use. They replied: "We use a mix of Staubli and other brands and have never received any...
